m risxmnue DEVICE r012. nu' romonnais.

' A'mfl sation filed January citizen of the United States, residing'at an Antonio,in the :county of Bexar and State haveinvented new and useful Antiskidding Devices for Automobiles, of which the following is a specification.

The' object of my invention is to improve the type'ef anti-skidding devices that comprise brake shoes ada beneath the rear whee s of an automobile, by the provision of a construction that is simple effective in operation and susceptible of bein quickly'applied and released.

To the attainment of the foregoing, the invention consists in the improvementto of Texas,

hereinafter described and definitely claimedfl In the accompanying drawings, forming part of this specificat1on:

Figure 1 is .a side elevation showing my.

. improvement in released position.

' Figure 2 is a side elevation with the improvement in applied position. Figure -3 is'a galnview showingthe Figure 4 is an enlarged 'fragmentarfy of perspective showing one of the shoes 0 the device and the connections complementary thereto. Similar numerals designate corresponding parts in all of the views of the drawlngs.

I illustrate my improvement in conjunc- 1 and the rear wheels by 2. A transverse s aft 3. is appropriately'sup-s t e ported and carried at the underside of rear portion of the chassis 1, and'pivotally connected at .4: to the said shaft. are arms 5.

' Each of. these arms5 is equi ped with atapered shoe 6 of steel or ot er approprlate material, the shoes -being concaved crew section at their rear; sides as desi%iatedb 7 so asto conform'to the tires on t e whee 2. In the connection of the shoes 6, the arms. 7 5 are provided at 8,with lateral 'ournal pins.

on which the shoes" are. pivota y mounted so that normally the shoes will rest in ndent-position on the arms as appears in igurel. Itwillalsobeunderstoodinth sconnection that when the arms-5 are swung Y downwardly, the shoes 6 by on f the und'wlllbe directedrearw y'soasto assure the shoes the position ted to be dropped mobile.

28.1925. Serial 11 5,346.

be noted that the said kerfs 9 are intersected 0 by the said journaled pins 8 so that heads 10 pivotally mounted on the pins 8 are enabledgto rest in the kerfs 9 and be held against lateral deflection by the same. The

' heads 1O are carried at the rear ends of the 12 with forward rods 13.

Journalled-at 14 in approprlate bearin on the chassis 1 is a transverse rock sha t rods 11 which areconnected by turn buckles 15 with cranks 16 at its ends, pivotally connected at 17 with the forward ends of the be rods 13. The said shaft 14 is also equipped with a hand lever 18 provided with a detent 19 for cooperation with a segmental rack 20 7 fixed to the chassis 1.

Interposed' between and connected to the forward ends of the rods 13 and the forward portion of the chassis are cables 21 preferably in the form 6 so as to enable the device to operate to the bestv advantage in braking the vehicle and in. preventing skidding thereof.

In ractice, the device when in released 95 state. as its parts ositioned as shown in Figures 1 and 3.' en however, the neces tween the wheels 2 and the roadway with 06 the result that the automobile will be' effeetively braked and skidding'of the automobile will be effectively prevented. For the release of the member it is simply necessary for the operator to swing the lever 18 100 rearwardly' and secure it in the position shown in Figures 1 and? when the device will be prevented from interfering in any degree withthe usual operation of the auto- By reference to Fi parent, thatthrough t V detent 19 with the se ental 'rack '20, the shoes 6 may, when' eemed expedient, be secured in the working position shown in re: 2 it will be "ap e cooperation of t of chains, and calculated, when the devlce is applied as shown in Fig: :ure 2' to limit the rear movement of the shoes e automobile driver to release the is necessary for the automobile to traverse a long stretch of slippery roadway,

-sufliciently light in weight, is susceptible of it-being- .of course necessary t operate the lever 18 in accordance "with the 'advance'o'f the autoready application to an automobile, and is effective inioperation, notwithstanding but 3 little effort for said operation is required.

Having described my invention, what I' v claim and desire to secure by Letters-Patent, is: I

An anti-skidding device for automobiles comprising'vertical swinging arms pivotally' oftheir upper Figure 2, this being advantageous when it 'connected with the automobile chassis and having lateral journal (pins, tapered shoes pivotally mounted on said journal pins and having rear sides of concave cross section and also having kerfs' in the forward sides portions, said kerfs being intersected by said journal pins, rods having heads disposed in said kerfs and pivotally connected to said journal pins, a transverse shaft journalled in bearings on the chassis andhaving"cranks atits ends, said cranks, pivotally connected to said rods, means for adjusting and adjustably fixing said transverse shaft, and cables interposed between and connected to the forward portions of said rods and the forward portion of the chassis.

In testimony whereof Iaffix my signature.

EDWARD HAAS.
